How to care for doorknobs

1. Open and close the door correctly
Some of my friends' doorknobs are easily broken because the door is closed in the right way. Generally speaking, when closing the door, you should first hold the doorknob, then screw the deadbolt into the lock body, and then close the door before letting go, so as to avoid the handle breaking due to too much force or incorrect way.
2. Clean frequently
Whether it is the lock body or the door handle, if there are stains in the process of use, the stains on it need to be cleaned in time to avoid corroding the door handle or penetrating deep into the lock body.
3. Take necessary protective measures
The lock will affect the smoothness of opening because of thermal expansion and contraction, especially in winter, when the season changes, the weather changes more obviously, and the temperature difference between indoor and outdoor is relatively large.
